(msys) perl readline creates sys$command files w/o STDIN connected

This fixes [perl #115900].
Rational findConsole dispatch for Term::ReadLine.

Back in 5.002 or so, if we didn't find /dev/tty and weren't on
Windows, the console was assumed to be sys$command, which only
makes sense on VMS (possibly $^O didn't work yet on VMS?).

Later accretions have assumed that the sys$command default meant
something other than laziness and a second if block with various
specific overrides was added, some of which set the console back
to undef after its having been set to sys$command.

That can all be avoided by simply checking we're on VMS before
setting the console to sys$command and letting it default to
STDIN for cases where we don't know of something else specific
that it should be.

Stop cv-to-glob assignment redef warnings from leaking

We should not increment the reference count of the assignee until we
are past the warnings.  It should only happen when the reference-
counted location is actually made to hold the assignee.

At the same time, I changed it to use a more specific variant of
SvREFCNT_inc, for speed.
Missing dependency in XS::APItest’s Makefile

When core_or_not.inc is modified, core.c and notcore.c should
be recompiled.
Move a CAN_COW_MASK comment from sv.c to sv.h

It got left behind in ed25273444 when the macro moved.

Consider /... a directory component with EFS on VMS.

For some reason the omnibus patch (360732b5267d5dfe) that brought
Extended Filename Syntax support to the VMS port considered three
dots part of the filename portion rather than part of the
directory portion when converting a Unix-format path to VMS format.

There's no reason this should be different with EFS, so make it
the same as without EFS, which gets two TODO tests passing.
Remove 3 unused interpreter variables

These variables have been unused in the Perl core since
commit 4c88d5e0740d796bf5064336d280bba72897f385.

The variables are undocumented.  The only real use of any of these I
found in CPAN is at
https://metacpan.org/source/ABERGMAN/Devel-GC-Helper-0.25/Helper.xs#L1
The uses there appear to be in a list of known Perl variables.  Since
the module was published, more than a few new variables have been added,
making this code obsolete anyway.
